DESCRIPTION
The OPA131 series of FET-input op amps provides
high performance at low cost. Single, dual and quad
versions in industry-standard pinouts allow cost-effec-
tive design options.
The OPA131 series offers excellent general purpose
performance, including low offset voltage, drift, and
good dynamic characteristics.
Single, dual and quad versions are available in DIP
and SOIC packages. Performance grades include com-
mercial and industrial temperature ranges.
